SPECIFICATION forming part of Letters Patent No. 582,396, dated May 11,1897'.

Application filed February 26,1897. Serial No. 625,200. (No modclfi ToaZZ whom it may concern:

Be it known that I, WILLIAM G. SCHNEE, a citizen of the United States,residing at Pueblo, in the county of Pueblo and State of Colorado, haveinvented certain new and useful Improvements in Insulators; and I dohereby declare the following to be a full, clear, an d exact descriptionof the invention, such as will enable others skilled in the art to whichit apro pertains to make and use the same.

My invention has relation to improvements in insulators for electricconductors; and the object is to provide a simple, effective, andreliable device of this class; and to this end the novelty consists inthe construction, combination, and arrangement of the sa1ne,as will behereinafter more fully described, and particularly pointed out in theclaim.

In the accompanying drawings the same reference-characters indicate thesan'ie parts of the invention.

Figure 1 is a perspective view of my improved insulator. Fig. 2 is asimilar view with the cap raised from the insulator. Fig.

3 is a top plan view of the insulator with the cap removed. Fig. 4: is avertical section of the complete insulator on the line of the conductor.Fig. 5 is a similar view taken at a right angle to the conductor.

1 represents the peg or post, the lower end of which is secured to thecross-arm of a telegraph-pole or other suitable support, and its uppercylindrical end 2 is formed with two ra dial lugs 3 4, the lower edge 5of each of which 5 forms a section of a spiral, being inclineddownwardly to the left hand from the vertical shoulder G to the oppositevertical parallel shoulder 7.

The insulator itself consists of an approxi- 0 matelybell-shaped hoodS,cylindricalin cross section and formed with a recess 9, the walls ofwhich are provided with an annular flange 10, having vertical cut-awayportions 12 12 for the reception of the lugs 3 a on the post 1,

5 and by giving said hood a quarter-turn to the right the inclined orbeveled edges 5 5 of the lugs engage the upper edge of the flange 10 andrigidly secure the hood in place. The

upper end of the hood 8 terminates in an integral semisphere 13, havingan annular horizontal flange lat.

15 15 represent two vertical rectangular guide-recesses on the oppositesides of the selnisphere, and 1o 10 represent rectangularretaining-recesses formed in the opposite edges of the flange it.

17 represents a longitudinal slot or groove in the semisphere 1-3 forthe reception of the linewire 18. The opposite walls of the groove 17are formed with the vertical projecting 6o ribs 19 12), thecontiguousfaces of which converge downward, and the ribs 1.) on the oneside are arranged to project into the spaces formed by the ribs 19' onthe opposite side, and vice versa, so that the line-wire will be bentout of line in a horizontal plane to effectually secure it in place.

20 represents a removable semicircular cap which projects over andencompasses the semisphere 13. The lower edges of this cap 20 are formedwith two inclined faces 21 21 and with two oppositely-disposed internallugs 22 22, and when the linewire 18 is placed in the groove 17 the cap20 is placed over the semisphere 13, so that the internal lugs 22 22pass freely down through the vertical reoesses 15 15, with the inclinedfaces 21 21 resting on the wire on each side of the semisphere 13. Thecap is then given a short turn to the right, which brings the lugs 22 inthe cap in line with the retaininp=recesses 16, the resiliency of theline-wire pressing upward on the faces 21, raising the cap to engage thelugs in said recesses and locking said cap against accidentaldisplacement.

23 represents a flexible disksuch as rubber, leather, or the lilelocated on top of the post 1, and when the hood 8 is secured in placethis disk acts as a spring to hold the hood into intimate contact withthe lugs on 0 the post. This manner of securing the wire in theinsulator is very rapid, economical, and effective, dispensing with thetime and expense incurred incident to the use of tiewires and permittingthe free expansion and contraction of the line, and should occasionrequire the entire line may be taken down as quickly and cheaply as itwas put up and with the line-wire in practically the same'condition.

While my improved insulator is preferably constructed of glass or othervitreous male rial, it is evident that it can be made of any suitableplastic non conducting substance without departing from the spirit ofthe invention.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is

An insulator comprising the post or peg 1, having the radial lugs 3 4,provided with inclined lower edges 5, and the flexible disk 23 mountedon the top of said peg, in combination with the bell-shaped hood 8, theinner walls of which are provided with a horizontal annular flange 10,having vertical cut-away portions 12 12, and having its upper end ter-
